The United States was not surprised by Russia's announced change in its nuclear doctrine and does not plan to adjust its own nuclear posture in response, a White House National Security Council spokesperson said on Tuesday.

Russian President Vladimir Putin seeks to intimidate the West by expanding the conditions for using nuclear weapons in Russia’s updated nuclear doctrine, German Foreign Minister Annalena Baerbock said on Nov.

President Vladimir Putin has updated Russia’s nuclear doctrine, two days after his American counterpart Joe Biden granted Ukraine permission to strike targets deep inside Russia with US-made weapons.
